Arduino Basic Tutorials

What is Arduino?
It is an open source programmable circuit that can be integrated into a wide variety of project including both simple and complex.

It is a programmable microcontroller that exactly gives a visual understanding of what your program does after uploading a program onto the board.






Introduced back in 2005 in Italy by Massimo Banzi.

Arduino Uno Board:

1. Reset Button: To restart any programs.

2. AREF: Analog reference and is used to set an external reference voltage.

3. Ground Pins.

4. Digital pins: Pin through 1-13 is digital input and output pins.



5. PVM (Pulse width Modulation): The pins marked with ~(tilde) signs can simulate an analogue output.

6. USB: used for powering the board and uploading the sketches.

7. TX/RX: Transmit and receive data indication LEDs.

8.  ATmega Controller: brain and stores the programs

9. Power LED indicators: The LED lights up when the power is on.

10. Power Regulators: Controls amount of power or voltages.

11.  Analogue Pins: Can read the analogue signals and convert to digital signals.

      Remark: Analogue is infinite values
                     Digital is discrete values.

Note: Arduino Needs 9Volt power Supply and if your Arduino needs to be mobile then it can be powered via USB cable.

       Remark: AC (Alternating current) where the direction of electric charge changes periodically.                            While DC (Direct Current) where the electric charge flows in one current.


Understanding Breadboard

It is an electric circuit where you can prototype projects.
Normally top and bottom two rows are connected horizontally and while others are connected vertically.

It is mandatory to have basic knowledge about electrical wiring to carry out projects in Arduino.






Prerequisites for Arduino:
